LOOK FOR AUTOMOBILES.

Specification of Letters Patent. P t t J 29,1920

Application filed August 1, 1919. Serial No. 314,613.

To all whom it may concern Be it known that I, HENRY A. KENDALL, a citizen of the United States, residing at the city of Baltimore, State of" Maryland, have invented certain new-and useful Improvements in Looks for Automobiles; and I do hereby declare the following to be a full, clear, and exact'description of the invention, such as will GHELbIGDtl'IGI'S skilled in the art to which it appertains to make and use the same;

adaptedto prevent the withdrawal of the My inventionrelates to the'construction of locks for automobiles, and especially to that class where clamp members containing will also effectively resist the removal of the clamp. "members from the steering column after application of the-same thereto. To this end the main'feature'of my invention involves the combination with interlocking'fclamp members adapted to inclose and bind upon the steering column and havinga'lined openings for the reception of a tubular lock-casing, of a tubular lock-casing adapted to interlock with-the clamp members and cause said clamp members to inclose and'bind upon the steering column.

A further feature of my invention involves, in conjunction with the above recited combination, the'fpr'ovision on the interior of'the tubularloc'k casing of projections lock from its tubular casing after it has been inserted and finally seated therein, whereby the disassociation of the combining elements is prevented without the application of destructive force. I

A further feature of my invention involves the combination with clamp members having alined threaded openings and an exter'nally threaded tubular lock casing, said clamp members and lock-casing having openings for the passage of the lock-bolt,

of a bushing adapted topbe introduced the clamp through the'tubular lock-casing and to con-,

stitute a guide and casing for the, lock-bolt. There are minor features of invention, all as w1ll heremafter more fully appear.

In the draw ngs chosen for the purpose of illustrating my invention, the scope where-- of 1s polnted out in the claims,

Figure l is a horizontal sectional view of an automobile lock embodying my invention, showlng its relatlon to the steering post and column of an automobile.

' Figs. 2 and 3 are detail sectional views of members.

F1g. 4 1s a horizontal sectional view, simito Fig. 1, but showing the method of insertmg the lock-bolt, after the clamp-members have been secured to the steering column.

Fig. 5 is a view in side elevation of the tubular lock-casing.

F 1g. 6 is a'longitudinal central section of the tubular lock-casing. I

Fig. 7 is an end caslnga I H Fig. 8 is aside elevation, and endviews, of the bushing and lock-bolt guide.

. Figs. 9, 10, 11 and 12 are views in end and side elevation of the lock.

Figs. 13 and 14 are sectional views of different forms of clam members adapted to steer ng columns 0 particular cross sectlons.

Like symbols refer to like parts wherever they occur. a I

In the drawings, S indicates the tubular steer ng column of an automobile and P the steerlng post of: shaft within the column.

members, or general outlines thereof, are matters ofselection and adaptation and as such are not involved in my invention.

7 In the principal figures of the drawing the clamp members are shown as adapted to a. cylindrical or General Motors steering column; in Fig. 1 3 as adapted to a Ford steermg column, and in Fig. 14 as adapted to a Maxwell steering column.

The clamp, which is adapted to inclose view. of thetubular' lock- .90 The cross section of 'thesteeringcolumn S will determine the form or outlineof'the clamp member, but the form of the clamp and bind upon the steering column to which the lock' is to be applied, is composed of a plurahty of members 1 and 2 provided with interlocking lugs 3 and recesses 4, or with equivalent means, for detachably connecting or interlocking the parts, and'at the contact-.

ing portions opposite thereto with alined and threaded openings 5 and 6 for receiving an externally threaded lock-casing 7 of tubular form adapted to interlock with the clamp members 1 and 2.

The meeting faces of the clamp members,

across the plane of which the tubular lock casing 7 passes, are preferably machined or smoothly finished so that when the clamp I members are secured in pesition on the steerjAt'their'meetmg p01 7 V H the clamp members or the faces in contact ing'column the line of parting will be indistinct. The tubular lock-casing 7 is preferably threaded on its exterior, as at S, for a su'liicientdistance to insure its engaging both of the clamp members. as to force them into the steering column S.

intimate contact with each other and with Ms on the interior of with the steerin column S, the clamp members are recessed asat 9 to constitute a slot for the passage of the lock-bolt, and opposite thereto the steering column S will be suitably slotted fora like purpose. The steer- "ing' 'post P will also be drilled or suitably v recessed to receivethe lock-bolt The tubular lock-casing 7, which when the clamp members 1 and'2 are applied tothe steering column and are interlocked as at 3 and 4 serves to' confine the clamp mem- V bersand cause them to bind on the steering column, is threaded as at 8 for that purpose and is pierced as at 10 for the passage, of the look-bolt and the reception of a bushing or guide 12 for the lock-bolt,

On the same side and in line with the bolt opening 10 the tubular lock casing 7 is provided on'its interiorwith a plurality of" triangul'arly disposed projections 11 'which may be produced by punching the walls of the tubular casing. These projectionsll not only engage and prevent the withdrawal of the lock afterit has been fully inserted inthe lock casing 7 but also in". v p

ik'thimble or bushing 12 of such dimensionsv that it canbe introduced through the preventthe rotation of the lock inthe eastubular casing 7 extends into the opening 10 in the tubular .casing,the opening 9 in the i clamp members, and the lock-bolt slot in the steering column; 7 L indicates a lock of any well known form adapted for use in the. tubular lockcasing 7,

Y said lock being provided with a member Z and lock-bolt pin 39 adapted to enter. an elongated slot 15 in the end of lock-bolt 13. The lock-bolt, 13 which is to be introduced through the lock-casing 12 after the clamp members 1 and 2 have been-secured in place by the lock-casing 7, is preferably eccentrically connected with the member Z of the look by a link member 14in which is formed an elongated slot 15 for the reception of the openings 5 and 6 for the reception of the threaded tubular casingmember 7 are then brought together with said openings in alinement and are tightly held until the.

threaded tubular casingmember 7 has been inserted and broughtinto position toengage both clamp members 1 and 2 andturnedtobring said members tightly togetherwith the hole 10 in the tubular casin 7 inalinement with the opening 9 throug the clamp members 1 and 2. T

e thimble bushing or guide memberf12 is now placed in position.

It is, together with the lock-bolt 13, introduced through the lock-casing 7 and ,forced into position in the openings 9 and1 0, by

means of'a screw driver or any suitable tool.

The steering post P is at this time manipulated by means'of the usual steering wheel until the lock-bolt can be pushed into the keeper slot in the steering post, afterwhich the lock cylinder L with the key inserted and turned to the locked position i is introduced into the tubular casing 7 and pushed down gnltil' the pin 12 engages in the slot of lock- While the lock is held in this pqsition the key is turned to the unlocked position and the steering post is moved to. ascertain whether the lock bolt is properly engaged .by the pin on the lock-member Z. If everything is found to operate properly the lock cylinder is pushed to its final posltion, thus allowing the projections 11 on the interior of the tubular casing 7 to snap into a recess Z or behind a shoulder on the lock cylinder,

thereby connectingthe several members comprising the automobile lock in a manner preventing disassociation'of the combined elements by any'force less than a destructive one. r I
